Fluid Construction Grammar (FCG) is an open-source computational grammar formalism that is becoming increasingly popular for studying the history and evolution of language. This demonstration shows how FCG can be used to operationalise the cultural processes and cognitive mechanisms that underly language evolution and change.

We present a theory of object-orientation on the basis of the re-nement calculus. This theory allows for specifying the behaviour of objects and provides a calculus for the proof of relationships between classes such as reenement. Given two similar, but not identical classes, we present an algorithm to construct a common superclass which is reened by both classes, and an algorithm to construct ...

This paper describes how object-oriented software construction principles allow to develop extensible and reusable building blocks for the development of data flow based visual languages. First we’ll present the data flow visual language ProtoHyperflow whose object-oriented realization is discussed in the second part of the paper.

Developing technologies that support collaboration requires understanding how knowledge and expertise are shared and distributed among community members. We explore two forms of knowledge distribution structures, coordination and cooperation, that are central to successful collaboration. We propose a novel method for detecting the coordination of strategic communication among members of politic...

This paper generalizes a method of generating shift sequences in the interleaved construction proposed by Gong. With the new shift sequences, some new families of p-ary sequences with desired properties can be obtained. A lower bound on the number of new families of binary sequences is also established.

A counterexample is given to the uniqueness result given in the paper by J.Cox and K.Thompson, Note on the uniqueness of the solution of an equation of interest in inverse scattering problem,

DNA is a promising construction material for the supramolecular 'bottom-up' engineering of artificial nanostructured devices. The use of DNA for the selective positioning of macromolecular components, the fabrication of nanostructured DNA scaffolds, as well as the DNA-templated synthesis of nanometer-sized and mesoscopic complexes, consisting of inorganic and bioorganic compounds, are exciting ...
